RE: [PHP] Session troubles

What do you have for the return values for your session_read function? (Specifically, what do you return when there's no data available?)

I am still unable to get my own session handler to work. My session handler's write never gets called; only my session_open and session_read get called....the default file session handler still works, if I change save_handler back to file instead of user. As for the feature request, I guess I could - is there a mechanism to do this outlined somewhere? > -----Original Message----- > From: Sean LeBlanc [mailto:seanleblanc@attbi.com] > Sent: Tuesday, January 01, 2002 8:32 PM > To: php-general@lists.php.net > Subject: Re: [PHP] Session troubles > > > On 12-31 09:23, Jaime Bozza wrote: > > Sean, > > From your php error_log, it's saying the following: > > Failed to write session data (user) > > > > which sounds like it's having problems writing to the user-defined > > session handler.
